Nothing on it can run flat, seize or need charging. The passenger's own weight drives the descent and a hydraulic governor keeps the speed under control.
A hydraulic governor limits descent to about 1.1 m/s for a 100 kg passenger.
If the attendant lets go, the loaded chair stops and holds itself on the stairs.
Gravity does the work, so a lighter staff member can move a passenger up to 136 kg.
Rubber tracks grip concrete, stone, tile, metal and fitted carpet.
Retractable wheels roll the chair across landings and corridors.
At 20 kg and 270 mm deep, it fits a stairwell cabinet on every floor.
Manufacturer data for the Garaventa Evacu-Trac CD7. Dimensions are confirmed at survey.

Based on 112 reviews
“We put one on every third floor. At 20 kg a single security guard can carry it up if it ends up on the wrong landing after a drill.”
“Nothing to charge is the whole point for us. Our older battery chair was flat at every second inspection.”
“The governor makes the descent feel controlled rather than heavy. Our wardens stopped dreading the drill.”
“The fifteen-year warranty settled the procurement discussion for a life-safety item.”
“Transfer height is lower than the other chairs we tried. Moving someone from a wheelchair took one person instead of two.”
“Vin Grace surveyed all four towers and told us honestly where a powered unit was needed instead.”

No. It is descent-only. For basements or below-ground levels, you need the motorised Garaventa Powertrac. Many buildings use both.
Up to 136 kg (300 lb). Gravity and the governor do the work, so a lighter staff member can bring down a heavier passenger.
No. It is entirely mechanical, so it is ready even during a total power failure.
A hydraulic speed governor limits the speed, and a failsafe brake holds the chair on the stairs when the attendant lets go.
It suits straight stairs up to about 35°. It must not be used on curved or spiral stairs. Our engineer confirms this at the free survey.
Typically one per evacuation stairwell or refuge area. At 20 kg, many sites keep one on every floor.
